WITN ESSES I I INVENTOR 4 BFM W ATTORNEY HARRY M. ALDERFER, OF LOWER PROVIDENCE, PENNSYLVANIA.

FAUCE T.

To all whom it may concern:

Be it known that I, HARRY M. ALDERFER, a citizen of the United States, residing at Lower Providence, in the county of Montgomery and State of Pennsylvania, have in vented a certain new and useful Improvement in Faucets, of which the following is a specification.

My invention relates to a new and useful improvement in faucets, and has for its ob ject to provide an exceedingly simple and effective device of the character which will be effective in operation and so arranged as to prevent leakage as the valve proper is conical in shape and will always produce a tight fit with the valve seat.

Another object of my invention is to provide a faucet with which it will be unnecessary to use washers.

A still further object of my invention is to provide a device of the character described in which the valve seat may be readily removed when it has become worn and is of no further use.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which- Figure 1 is a longitudinal sectional view of a faucet made in accordance with my improvernent, the valve being shown in elevation. Fig. 2, a section at the line a:-m of Fig. 1 looking in the direction of the arrows. Fig. 3, a section at the line y-@ of Fig. 1 looking in the direction of the arrow, and Fig. 4, an end view of the valve seat.

In carrying out my invention as here embodied, A represents the body of the faucet having threads B formed in proximity to the outer end provided with a key A and an internal lug C in which is formed the circular groove D, with which engages the circular projection E formed on the inner surface of the valve seat F, said valve seat having a key way F formed therein engaging the key. The opening G in said valve seat is conical, into which fits the conical valve I-I attached to the end of the valve stem I, having the threads J formed thereon.

Specification of Letters Patent.

Application filed February 23, 1909.

Patented. July 13, 1909.

Serial No. 479,412.

With the valve seat F is formed the extension F for the purpose to be hereinafter described.

The threads J are adapted to engage with the threads K formed in the head L, said head having external threads if which engage with the threads B formed in the body A for holding the head in position.

In the lower portion of the head L is formed the opening N through which any water may pass that might ooze its Way between. the threads J and K into the outer portion of the head L, from which place it will pass down Ward and out through the discharge spout O.

VJhen the head L is in position in the casing the inner surface thereof will rest against the outer end of the extension F thus holding the valve seat in its position against the internal lug C.

In practice, the valve seat F is placed in the body A, the projection E entering the groove 1), thus forming a water tight joint. The valve H having been threaded into the head L is next placed in position. by threading said head into the outer end of the body A, then by turning the stern I by means of the handle P the valve II will be forced on to the valve seat, thus shutting off the flow of water, and by turning the handle P in the opposite direction the valve will he released. from the valve seat, allowing the water to flow, and should any of this water pass between the threads J and I; it will at once drop down and pass through the opening N into the body of the faucet, then out of the discharge spout 0, thus producing a faucet which is unlikely to leak, and one which will be effective in operation.

Of coure I do not wish to be limited to the exact details of constructionhere shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is- 1. A faucet having a body provided with internal threads in proximity to its outer end, an internal projection having a circular groove formed with said body, a discharge spout leading from said body, a head having internal and external threads formed therewith adapted to be threaded into the outer end of the body, a conical valve, a valve stem having threads formed thereon secured to said valve, a handle attached to the outer end of the valve stem, and a conical valve seat provided with a circular projection adapted to loosely fit within the body so that the projection enters the groove, as specified.

2. A faucet having a body provided with internal threads in proximity to its outer end, an internal projection having a circular groove formed with said body, a discharge spout leading from said body, a head having internal and external threads formed therewith adapted to be threaded. into the outer end oi the body, said head having a hole formed in the lower portion thereof, a conical valve, a valve stem having threads formed thereon secured to said valve, a handle attached to the outer end of the valve stem, and a conical valve seat provided with a circular projection adapted to loosely fit within the body so that the projection enters the groove, as specified.

3. In a 'l'aucet, a body provided with inter nal threads in proximity to its outer end and having a discharge spout leading therefrom, a conical valve seat, means for holding said valve seat in position, a conical valve, a valve stem having threads thereon formed with said valve, a head having internal and external threads and provided with means for allowing the water to pass of? from within, and means for turning the valve, as shown and described.

4. A faucet having a body provided with internal threads in proximity to its outer end, an internal projection having a circular groove formed with said body, a key formed on the inner surface of the body, a discharge spout leading from said body, a head having internal and external threads formed therewith adapted to be threaded into the outer end of the body, a conical valve seat provided with a circular projection and a key way adapted to be loosely fitted within the body so that the projection enters the groove, an extension formed with said valve seat, a conical valve, a valve stem having threads formed thereon secured to said valve, and a handle attached to the outer end 01' the valve stem, as specified.

In testimony whereof, I have hereunto alfixed my signature in the presence of two subscribing witnesses.
